SPECIFICATION forming part `f Letters Patent N0. 708,926, dated September 9, 1902. Application filed` December 26, 1900. Serial No. 41,117. (No model.)

To all whim/tit may concern,.-

Beit known that we, CRANMER S. SHA'rrUc and CLARK E. SHATTUG,citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Vapor-Burners, of which the following is a specification.

This invention relates to a certain new and useful improvement in vapor-burners by which the heavier or other grades of hydrocarbon oils can be successfully vaporized and burned, and thus enable them to be used for cooking and heating purposes, and to do this in such a manner as to avoid the production of smoke and smell and at the same time produce an intense heat with a comparatively small consumption of fuel.

The invention aims to construct a burner of the above-referred-to class which shall be extremely simple in its construction, strong, durable, and efficient in its use, and comparatively inexpensive to manufacture; and it consists of the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like numerals of reference indicate corresponding parts throughout the several views, and in which-- Figure lis a side elevation,partly in section, of the vapor-burner in accordance with our invention. Fig. 2 is a sectional elevation of a portion of the secondary vapor-burner.

Referring to the drawings by reference-numerals, 1 indicates the generating-chamber, whicl1,as shown,is substantially semispherical in contour, although various forms may be employed. The bottom 2 of the generator 1 is provided with a pair of openings 2 3. The former has secured therein the upper branch 4 of the oil-supply pipe and the latter the vapor-outlet pipe 5.' The bottom 2 projects outwardly from the generator, forming a shoulder or ridge 6 with a beveled edge. The function of shoulder or ridge will be hereinafter described. The lower end of the section 4is connected to the intermediate branch 7 of the oil-supply pipe by the union 8. The section 7 is in communication with the auxiliary generator 9, connected to the oil-supply by means of the branch 10, the branches 4, 7, and forming the oil-supply pipe. Surrounding the auxiliary generator or arranged below the same and connected thereto in any desirable manner is the oil-cup 1.1, the function of which will be hereinafter described. The auxiliary generator 9 and cup 11 may be of any preferred construction, but, as shown, are substantially cylindrical. The branch 10 is adapted to extend downwardly from the bottom of theauxiliary generator 9,as shown, so that the end of the latter may be fitted with a valve-stem 12, carrying a needlevalve 13, operated by means of the handwheel 14'. The valve 13 is adapted to regulate the supply of oil to the generator 1 through the branches 4 and 7. The vapor-outlet pipe 5 for the generator 1 is connected at its lower end to the vapor-reservoir 14, as shown, substantially similar to a pipe-elbow, although other forms of reservoirs may be employed. The free end of the reservoir 14 is closed by means of the plug 15; but this end may be sealed in any preferable manner. The top of the reservoir 14 is formed with a cone-shaped hollow projection 16,forming a valve-chamber for the needle-valve 17, carried by the vertically-arranged stem 18,which extends through the reservoir 14 andis operated by means of the hand-wheel 19. The hollow projection 16 is provided with an outlet-port 20 for the vapor, the needle-valve regulating the flow of vapor to the main burner, hereinafter described, through the port 20. Secured to the reservoir 14 is an exteriorly-screw-throaded coupling 21, having an opening forming a valve-chamber for `the needle-valve 22, carried by the horizontally arrangedstern 23, projecting through the reservoir 14 and operated by a suitable hand wheel. (Not shown.) The valve-chamber of the coupling 21 communicates with a port for supplying vapor from the reservoir 14 to the supply-pipe 25 of the secondary burner, to be hereinafter described, the supply-pipe 25 being connected to the coupling 21, asshown. The valve 22 is adapted to regulate the supply of vapor from the reservoir to the secondary burner through the supply-pipe 25, to which is connected at its free end, as at 27, an upwardly-tapering hol- IOO low elbow 28, carrying a screw-threaded cap 29, provided with an outlet-port 30 for supplying gas or vapor to the secondary burner.

The reference-numeral 31 denotes a spreader formed of a substantially convex continuons I plate,which is suitably secured to the branches 4 5 and provided with an annular flange 32, terminating at its top in a shoulder 32. The spreader 3l has a centrally-arranged contracted opening 33 for the passage of the gas or vapor to the main burner 34. The spreader 31 is formed in a substantially convex manner' to leave only space enough between the generator and burner so that the gas will pass around the spreader and be projected th rough the burner with more force than if the spreader were not employed. If the spreader were not convex, it would leave too much space between the same and the generator and burner and in some instances cause the ignition of the gas within said space. This igniting of the gas within the space mentioned is the objection overcome by constructing the spreader in the manner set forth. The smaller the space between the generator, spreader, and burner the more evenly the gas spreads and the more forcibly it is projected through the burner. As gas passes through the contracted opening 33 of the spreader it strikes the bottom of the generator 1 and rebounds back upon the spreader 31, which, being convexed, spreads the gas and causes it to be evenly distributed or projected through the burner 34. The main burner 34 consists of a conical ring of such height that its lower end will rest upon the fiange of the spreader 3l, and its inner face at the top thereof is formed with a shoulder 35, which engages the shoulder or ridge 6 of the bottom of the generator. The burner 34 is formed on its inner face with a series of circumferentially-arranged ribs 3G, and between each pair of ribs 36 is arranged a series of circumferentiallyextending elongated jet openings or passages one above the other, extending from rib to rib. Arranged above the supply-pipe 25 for the secondary burner 37 is a spreader of a similar construction as the spreader 31. The secondary burner 37 is substantially convexed in cross-section and is provided on its inner face with a series of ribs 3S, and between each pair of ribs 3S is arranged a series of circumferentially-extending elongated jet openings or passages one above the other, extending from rib to rib. The burner 37 is closed at the top, and in this particular is different from the main burner, as the top of the latter surrounds the generating-chamber.

The reference-numeral 39 denotes a hanger for supporting the pipe 25.

The operation of the device is as follows: Oil being supplied to the auxiliary generator i), the same is vaporized by means of igniting the oil in the cup 11, which is arranged in the manner shown, the vapor passing through the generator 1, reservoir 14, through the open` ing to the main burner 34, and it is then ignited, thereby vaporizing the oil in the generator 1, which has been fed thereto by the oil-supply pipe. When the oil has become vaporized in the generator 1, the vapor passes to the reservoir 14, thence through the opening 33 in the spreader 31 to the burner 34. The opening in the spreader is of such size that all of the vapor as it leaves the reservoir will pass to the burner 34, where it will be ignited. As the spreader 31 is formed of a continuous plate, with the opening 33 at the top thereof, it will be evident that the vapor will pass from the reservoir to the burner through the opening in the spreader. The flame of the main burner is regulated by the valve 17. The vapor or gas from the reservoir 14 is fed to the secondary burner by means of the supply-pipe 25 and its connections. The flame of the auxiliary burner is regulated by the valve 22. The supply of oil to the generator 1 is regulated by means of the Valve 13. By arranging the spreader 31 in the manner shown above the vapor or gas outlet of the reservoir 14 and elbow 2S the vapor or gas is mixed with a suitable quantity of air before passing to the burners, and by arranging the generator 1 above the main burner 34 it will be evident that rapid generation of gas or vapor will take place and that constructing the burners in the manner shown the heat will be expelled, so the same can be utilized for heating purposes.

It is thought the many advantages of our improved construction of vapor-burner can be readily understood from the foregoing description,taken in connection with the accompanying drawings, and it will be noted that various changes may be made in the details of construction Without departing from the general spirit of our invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
